Bug ID: 98027
Summary: CET support is documented to be explicitly enabled,
however it's enabled by default
Product: gcc
Version: 10.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: doko at debian dot org
Target Milestone: ---
CET support is documented to be explicitly enabled, however it's enabled by
default.
install.texi reads:
@item --enable-cet
@itemx --disable-cet
Enable building target run-time libraries with control-flow
instrumentation, see @option{-fcf-protection} option. When
@code{--enable-cet} is specified target libraries are configured
to add @option{-fcf-protection} and, if needed, other target
specific options to a set of building options.
The option is disabled by default. When @code{--enable-cet=auto}
is used, it is enabled on Linux/x86 if target binutils
supports @code{Intel CET} instructions and disabled otherwise.
In this case the target libraries are configured to get additional
@option{-fcf-protection} option.
however it's still enabled when no --enable-/--disable-cet configure options is
given.
Please either update the documentation or the behavior. Seems to be the case
for the gcc-10 branch as well.
unreleated question: when do you configure with -fcf-protection -mshstk, and
when just with -fcf-protection?

I think support is autodetected now. HJ, can you adjust the wording?
